SPECTAOLE-FRAIVIE FOR SIGNALS.

SPECIFICATION forming part of Letters Patent No. 770,462, dated September 20, 1904.

Application filed April 16, 1903. Serial No. 152,895. (No model.)

' To all whom, it may concern.-

Be it known that I. REINHOLD HERMAN, a citizen of the United States of America, residing at Grafton, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Spectacle- Frames for Signals, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in spectacle-frames for semaphore-signals; and the invention has for its primary object to construct a spectacleframe with a plurality of openings, whereby the same frame may be used in connection with the two-position signal or in connection with a signal having any number of positions, according to the number of openings in the spectacle-frame.

A further object of my invention isto construct a spectacle-frame in which the greatest amount of weight exerted by the frame or casting against the semaphore-arm will be applied when the semaphore-arm is in the danger or red position.

A still further object of the invention is to provide a spectacle-frame equally adapted for connection of a lamp or other light with a supporting-post at various points, and, further, to construct a spectacle-frame with means whereby the lens carried by the frame may be adjusted, whereby to focus with the lamp without necessitating the changing of the latter.

Briefly described, the invention comprises a spectacle-frame having a somewhat sectorshaped form, which frame is mounted on a journal or pin carried by the supportingpost, the semaphore-arm being suitably connected to the frame. This frame is provided with a plurality of openings which are all on the same are, and to the back of the frame is adjustably fitted lens-holders, in which the lens is eccentrically mounted. This construction, together with other features entering into my invention, will be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forminga part of this specification, and wheretion.

in like numerals of reference indicate like parts throughout the several views, in which Figure 1 is an elevation of my improved spectacleframe, showing the same supported on a signal-post, the latter being partly broken away. Fig. 2 is a detached detail plan View of one of the adjustable lens-holders. Fig. 3 is a transverse vertical sectional view of the same. Fig. 4 is an elevation of a part of the post, showing the adjustable lamp-bracket. Fig. 5 is a plan View of a part of the spectacle-frame, showing a modified form of construction of lens-holder.

To put my invention into practice, I provide a spectacle-frame embodying a'casting l, which is somewhat sector shape in form and has the semaphore-arm 2 suitably connected thereto at a desired point. This casting is constructed with a journal or hub 3 for mounting upon the journal-pin 4, by means of which it is supported on the signal-post 5. The spectacle-frame is provided with a plurality of openings all on the same arc, and in the present illustration of my invention I have shown five of these openings, (designated 5, 6, 7, 8, and 9, respectively.) In use, assuming that the signal being used was a threeposition one, then the opening 9 would have the lens for the red or danger position, the opening 8 would be brought into registration with the lamp at caution or clear position, and the lens in opening 7 would be moved into registration with the lamp when the signal was at clear or white posi- In this same connection, however, it will be observed that were the lamp attached to the signal-post at a point adjacent to the support of the spectacle-frame the lens in opening 7 would be for danger or red position, the lens in opening 5 for clear or white position, and lens in opening 6 for caution or clear position. The glasses or lens 10 are eccentrically mounted in the concentric lensholders 11, provided with flanges 12, having slots 14: to receive the bolts or screws 15, by means of which the lens-holders are secured to the back of the spectacle-frame or casting. The lens or glasses 10 are fastened to the holder by means of an annular clampring 16, attached to the holder by tap screws 17 or in any other suitable manner. The lamp (not shown) may be supported from post 5 by means of a sleeve 18 or other form of clamp for engagement with the'post, which is secured in the adjusted position by means of the set-screw 19, and this sleeve carries an arm or rod 20, on which the lamp-bracket 21 is adjustable and which bracket is secured in the adjusted position by means of the set-screw 22.

In order to offer as little resistance to the wind as is possible, I may construct the lensholders with openings 23, (seen in Fig. 5 of the drawings,) the lens-holders in other parts being the same in construction as were above described.

With this construction of semaphore-cast ing or spectacle-frame it is to be observed that in case the lamp is supported from the post in a particular position, and may perhaps not be adjustable, the glass or lens holders may be rotated, soas to bring said glass or lens into focus with the lamp, as will be observed by reference to dotted position shown in Fig. 1 for the lens-holder secured over the opening 7. Thus, for instance, were the lamp supported on a ten inch standard bracket while the semaphore-casting was constructed for a thirteen-inch or fourteen-inch standard lamp-bracket the lens-holder would be rotated so as to bring the lens into focus with the lamp, thus permitting the use of the same semaphore-casting or spectacle-frame for different standards or lampbrackets. Likewise if the lamp were supported from the post at an angle the lens-holders could be adjusted so as to cause the lens to properly focus with the lamp.

I desire to call attention to the fact that the greatest weight of the spectacle or semaphore casting is exerted against the semaphore-arm when the latter is moving into the danger or red position, and consequently the weight exerted against the semaphore-arm as the latter assumes its position intermediate the danger or red position and white or clear position is increased correspondingly in proportion to the counterweight exerted by the semaphoreblade.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A spectacle-frame comprising a casting provided with a plurality of openings all on the same are of the circle, and adjustable lens-holders carried by the spectacle-frame back of each opening, substantially as described.

2. In combination with a spectacle-frame of substantially sector shape whereby its greatest weight is offered to the semaphore-arm when the latter is moving into the danger position, of an adjustable lens carried by said spectacle-frame, substantially as described.

3. In combination with a spectacle-frame, a lens mounted in said frame and being adjustable in an arc of a circle, substantially as described.

4. In combination with a spectacle-frame, a plurality of lens mounted in said frame being independently adjustable in arcs of circles, substantially as described.

5. In combination with a spectacle-frame, a lens-frame rotatably mounted in said firstnamed frame, substantially as described.

6. In combination with a spectacle-frame, a lens rotatably mounted in said frame, and means for securing the lens in its adjusted position, substantially as described.

7. In combination with a spectacle-frame provided with a plurality of openings all on the same are of a circle, a plurality of lensholders carried by the frame, one for each opening, said lens-holders having the lens eccentrically mounted therein, substantially as described.

8. The combination with the spectacleframe, of adjustable lens-holders carried by said frame, and lens eccentrically mounted in said holders, substantially as described.

9. The combination with a spectacle-frame,- of an adjustable lens-holder carried by the frame, and a lens eccentrically mounted in said holder, substantially as described.

10. In combination with a spectacle-frame,a lens-frame rotatably mounted therein.

11. In combination with a spectacle-frame, a plurality of rotatable lenses disposed in a common arc'of a circle.

12. In combination with a spectacle-frame, a plurality of rotatable lenses adapted to be successively moved in front of a light.

13. In combination with a spectacleframe,a plurality of lens-frames, and lenses eccentrically mounted in said frames.

14. In combination with the spectacle-frame formed with a circular opening, a lens-frame rotatably mounted in said opening.

15. In combination with the spectacleframe, a lens-frame rotatably mounted in said spectacle-frame, and a lens mounted in said last-named frame in such rotation thereto as to be moved, into and out of focus with the rays of a light when the lens is rotated.

In testimony whereofI affiX my signature in the presence of two witnesses.

REINHOLD HERMAN.
